ATTACHMENT FOR LATERALLY-swlNGlNG AWNING ARMS.

Application filed October 25, 1926.

This invention relates to attachments for laterally swinging awningarms, and is more particularly directed to an attachment adapted to beconnected between pivoted arm sectious of the laterally swinging arms soas to yieldably urge the same to maintain a tension in the awning.

Awnings as now used to shade display windows and the like are of suchconstruction that the same sag after a short period of use, so thatduring rain or the like, the same catch and hold a considerable quantityof water which may then be spilled by wind or the like onto pedestrianspassing under the awning. The particular awnings concerning which thisinvention is related are those types of awnings which are rolled up upona roller when not in use, and after a period of use of these awnings thesame roll up so loosely on the rolls as to greatly shorten the lifethereof.

it is therefore an object of this invention to provide an attachment forlaterally swinging awning arms, that is adapted to be secured betweenthe arm sections of such a collapsible awning arm to yieldably urge thesame to the extended position, so as to maintain at all times a tensionin the awning.

Other objects and advantages of this invention will be apparent from thefollowing detailed description of a preferred embodiment thereof, asillustrated in the accompanying drawings, in which drawings,

Figure 1 is a fra-gmental plan View of an awning illustrating theadaptation of an at tachment embodying this invention thereto.

Figure 2 is an end section taken on the line 2-2 of Fig. 1.

Figure 3 is a fragmental sectional bottom plan view of an awningattachment embodying this invention.

In the preferred embodiment of this invention illustrated in theaccompanying drawings, 1 designates a roll on which the awning cloth 2is rolled. The roller 1 is secured in position on the face of a buildingin any desired or preferred manner, as is well understood in the art.Secured to the forward edge of the awning cloth 2 is an awning pole 3,and interposed between the awning pole 3 and the face of the buildingare laterally swinging awning arms 4.

The awning arms 4 are preferably constructed of a bracket 5 which isrigidly affixed to the face of the building below the roller 1, asillustrated at 6. The brackets 5 are pivotally secured at pins 7 to arms8. The arms 8 Serial No. 143,821.

are pivotally secured at their opposite ends at pins 9 to awning polearms 10. The awning pole arms 10 are pivotally secured at their outerextremities at pins 11 to brackets 12 which are secured to the awningpole 3.

The awning arms 4, as the awning cloth 2 is rolled upon the roll 1,collapses laterally and are so constructed that when the awning cloth 2is rolled down to the position illustrated in Fig. 1, the same are notat or do not pass center, so that when the roller 1 is actuated, thearms 4 will collapse into the desired position. Interposed between thearms 8 and 10, or between the awning pole 3 and the arm 10, or betweenthe bracket 5 and the arm 8, are spring tension means 13 which areprefer ably of the following construction:

A disc 14 is formed with a hub 15 at its center, and the pivot pin 9 ispassed through the hub 15 and is secured in position by means of a nut16. Formed on the upper face of the disc 14 is a projecting lug 17 whichengages the side of the arm 8. Formed integral with the disc 14 is acircumferential flange 18, providing a cylindrical body within which acoil spring 19 is mounted around the hub 15. One end 20 of the spring 19is passed through a slot 21 formed in the flange 18, and is therebysecured in position. A cover plate 22 is provided which has formed atits center a hub 23, which has a center bore of sufficient di ameter topermit the same to pass over the hub 15 formed in the disc 14. Formed inthe hub 23 are a plurality of diametrically opposed slots 25 into anyone of which. the bent end 26 of the spring 19 may be fitted. Pivotallysecured at ears 27 formed integral with the cover plate 22 on a pin 28is an arm 29 which is formed at its opposite end in an angle section 30.

- In adapting this attachment to an awning arm 4, any one of the pivotpins 7, 9 or 11 is first removed and the same is passed through the hub15 of the disc 14, so that the lug 17 engages either the bracket 5, arm8 or awning 10, depending upon which one of the pins 7, 9 or 11 ispassed through the hub 15. The cover plate 22 is then positioned so thatthe end 26 of the spring 19 passes through the correct slot 25 formed inthe hub 24 of the cover plate 22. The cover plate 22 is then rotated toimpart a tension to the spring 19, and the arm 29 is rotated on its pin28 into position so that the angle section 30 thereof will engage eitherthe arm 8, 10 or the awning pole 3. By means of the plurality of slots25 formed in the hub 24 of the cover plate 22, an adjustment is providedwhereby any desired or predetermined tension may be imparted to thespring 19.

IViththe attachment position as shown in Fig. 2, there is maintainedupon the arms 8 and 10 a spring'tension which at all times yieldablyurges the same toward the extended position so as to maintain a tensionin the cloth 2 and prevent the same from sagging. The spring tensionmaintained by this at tachment also takes up any wear or stretch thatmay ,occur in the awning cloth 2.

In order to prevent the arms 8 and 10 from swinging to a straight lineposition or past center, the awning arm 10 is pivotally secured at thepin 9 to the awning arm 8 so that its inner edge 31 engages the face ofthe hinge plate bracket 32 through which the pin 9 is passed. 1

Having fully described the preferred embodiment of my invention, it isto be understood that I do not wish to be limited to the exact detailsherein set forth, which may obviously be varied without departing fromthe spirit of my invention as set forth in the appended claims.

I claim 1. In combination with a laterally swinging awning arm, abracket, an arm pivotally secured to the said bracket, an awning pole,an arm pivotally secured to the awning pole at one end and pivotallysecured to the first said arm at the other end, of a disc mounted on thepivot between the said arms and having a lug adapted to engage the firstsaid arm,

spring means mounted on the said disc and secured thereto at one end, aplate mounted on said pivot pin and secured to the said spring at itsother end, and an arm secured to the said cover plate and adapted to beengaged with the second said awning arm.

2. In an attachment for laterally swinging awning arms, the combinationof a disc hav ing a central hub through which a pivot pin between twoarms of the said laterally swinging awning arm passes, a lug formedintegral with the said disc and adapted to engage one of said arms, acover plate, spring tension means interposed between the said coverplate and the said disc, an arm pivotally secured to the said coverplate and having an angle section at its end adapted to engage the otherof said awning arms.

In an attachment for laterally swinging awning arms having a pair ofarms pivotally secured together at their ends, the combination of a discadapted to be mounted on the pivot connection between said arms andhaving a projection adapted to en a e one of said arms, spring tension.means mounted on the said disc and secured at one end thereto, a coverplate, means formed integral with the cover plate for adjustablysecuring the same to the other end of said spring means, and an armpivotally secured to the said cover plate and adapted to engage theother of said awning arms.

Signed at Los Angeles, California, this 18 day of October, 1926.
